Sentry is the leading open-source application monitoring platform for tracking errors, performance issues, and exceptions in web and mobile applications. When an error occurs in production, Sentry captures full context — stack trace, user information, browser/OS data, and breadcrumbs of preceding events — and alerts the responsible developer immediately. Supporting 100+ platforms and frameworks, Sentry has become the standard error monitoring tool for development teams of all sizes.

The trade-off
Pros and cons
Pros
- Full error context including stack trace, user info, and event breadcrumbs makes debugging fast
- Source maps integration shows the exact line of original TypeScript/JSX code that caused an error
- Performance monitoring tracks transaction latency, database query times, and N+1 query detection
- Open-source core enables self-hosting for teams with data sovereignty requirements
- Industry-standard tool — most developers are familiar, reducing onboarding friction
Cons
- Can generate very high volumes of alerts without proper noise reduction configuration
- Pricing scales by error event volume — high-traffic apps with many unique errors can be expensive
- Performance monitoring features require additional configuration beyond basic error setup
- Retention periods for events are limited on lower plans — extended history costs more
